Specification of Letters Patent.

Patented July 13, 1909.

Application :filed March 19, 1909. Serial No. 484,550.

To all whom fit may concern:

Be it known that I, EDWARD Y. citizen of the United States, residing atCleveland, in the county of Cuyahoga and State of Ohio, have invented acertain new and useful Improvement in Trolleys, of which the followingis afull, clear, and exact description, reference being had to theaccompanying drawings.

My prior patent No. $745,367, issued Dee. 17, 1907, shows a trolleyadapted to be mounted on the lower flange of an I-beam and havingllangeless supporting wheels and lateral guide wheels whereby thetrolley may easily operate on a curved track way.

The present invention is an improvement on the trolley shown and claimedin the patent referred to, and comprises a very simple and efficientadjustment by which the same trolley may operate on trackways ofdifferent widths. There are certain standard sizes of I-beams, the lowerflanges of which have different widths, and I provide the trolley in thepresent invention not only with adjusting means, but with means forlocking the guide wheels in several positions which are selectedaccording to such standard width of flanges. 1

The invention is hereinafter more fully explained and is summarized inthe claims.

In the drawings, Figure l is an end view of a trolley embodying myinvention, the same being shown in place on a supporting track way,which is of Ibeani construction; Fig. 2 is a horizontal section throughthe web of the beam and the trolley frame just above the guide wheels;Fig. 3 is an enlarged vertical section through one of the guide wheelsand the adjacent portion of the frame; Fig. 4 is a bottom View of suchportion of the frame, showing the means for holding and locking theguide wheel support; Fig. 5 is a perspective view of such support.

Referring to the drawing by reference characters, A represents asuitable trackway which is shown as a standard I-beam hav- MOORE, `a

- ing the usually lateral projecting lower flange a.

B represents the frame of the trolley, which is shown as standingbeneath the lbeain flange and extending upwardly on the two sidesthereof, being made in two parts which are provided with downwardlyextending flanges b which are bolted together by the bolts C. Thistrolley frame may The frame shown has at its outer edges upwardlyextending webs b', from the upper end of which webs b2 extend inwardly,and from the inner ends of the latter webs project j flanges 3 whichextend upward, as shown,

and `preferably incline outwardly. These flanges b3 carry suitable studsE on which are journaled the' supporting wheels F. These wheels arellangeless and rest on the upper surface of the I-beam flange, as shown.

rIhe construction described in the last two paragraphs is shown andclaimed in my prior patent referred to. In that patent the trolley isguided by lateral wheels which are carried on journals rigidly mountedin the frame. In the present invention l provide the lateral guidewheels, but I journal them adjustably. These guide wheels are designatedGr. They are located between the upper surface of the main portion ofthe frame B and the under surface of the inwardly projecting webs b2 andare mounted on journal pins L.. These pins consist of reducedeccentrically placed extensions of cylindrical blocks or pins H, whichare mounted in the main frame B. In this construction it will beapparent thatv if the cylinder Il is turned on its axis the wheel Gr iscaused to approach or recede from the ange a.

To provide simple means for holding the pin I-l in the desired position,I preferably extend it below the frame B (which may be formed with aboss b4 at this point), and I provide it with a laterally extending eyeJ which is adapted to stand just below the frame and which may receive ascrew K passing through the eye into the frame. This eye may be veryconveniently constructed and mounted by making it in the form of a splitpin occupying a hole /L in the pin H. I provide a number of screwlthreaded openings in the boss 54, any of which are adapted to beoccupied by the screw K, two of these openings, designated b5 and Z2, asshown in Fig. 4, in addition to the opening occupied by the screw K.l

It will be seen from the above description that I have' provided anextremely simple method for adjusting the position of the wheels G andfor holding them in any of a number of positions. The removal of thescrew K allows the pin H to be turned on its axis as desired, or removedentirely for removing the wheels Gr. The curved broken lines in F ig. 2illustrate a curved trackway on which my trolley is ada ted to runequally well with a straight trac way, due to the omission of theflanges on the supporting wheels and the employment of the lateral guidewheels, while the adjustment provided adapts it to various trackways.

` I have shown the adjustment adapted for three positions which may veryconveniently correspond to I-beams having siX inch, seven inch or eightinch flanges, respectively, which are standard sizes. These dimensions,however, are only given-as illustrative, and I do not intend to limitmyself thereto. In fact not only may changes of proportion be madewithout departing from my invention, but

various mechanical equivalents may be em.

ployed if desired, and I do not intend to limit myself in the followingclaims further than the state of the art requires.

Having thus described my invention, what I claim is:

l. In a trolley, the combination with supporting wheels, lateral guidewheels, and means for adjusting said lateral guide wheels and lockingtheir journals in .fixed position.

2. A trolley adapted to run on the flange of a depending trackway andhaving in combination ilangeless supporting wheels, lateral guidewheels, and means for adjusting said lateral guide wheels.

3. In a trolley adapted to ride on the flange of a depending support,the combination of a frame adapted to extend beneath such support andproject upwardly onto opposite sides thereof, flange wheels carried bysuch upward projections and tracking on the flange of the support, andguide wheels mounted on vertical axes on opposite' sides of suchsupport, and means for moving sa1d axes. v

4. In a trolley, the combination with a.

frame, supporting wheels, guide wheels, adjustable journals for theguide wheels, and means for holding said journals in Various fixedpositions.

5. In a trolley, the combination of a frame, supporting members, guidewheels, and eccentric adjustments for the journals of the guide wheels.

6. In a trolley, the combination of a frame, supporting wheels, guidewheels, eccentric pins carrying the guide wheels and mounted in theframe, and means for locking said pins in diierent positions.

7. In a trolley, the combination of a frame, a guide wheel, an eccentricpin journaling the guide wheel and mounted in the frame, and an eyeprojecting from the pin and formed to receive a screw passing into theframe.

8. In a trolley, the combination of a frame, a supporting wheel, a guidewheel, an eccentric pin mounted in the frame carrying the journal of theguide wheel and hav ing a hole in it, a pin formed with an eye occupyingsaid hole and standing adjacent to the frame, and a screw adapted topass through said eye into the frame.

9. In a trolley, the combination of supportin wheels, guide wheels,adjustable journa s for the guide wheels, and means for holding saidjournals in one of a plurality of positions selected according tostandard sizes of the supporting trackway. I

In testimony whereof, I hereunto aliiX my signature in the presence oftwo witnesses.
